What is the area of the polygon shown below?

66

Step-by-step explanation:

first you find the area of the rectangle

5*12=60

then you find the area of the triangle

to find the length of the dotted line you need to subtract 9 from 12 which is 3

to find the length of the line adjacent to the dotted line you need to subtract 5 from 9 which is 4

use the triangle area formula 3*4*1/2=6

add the areas of the triangle and the rectangle 60+6=66
